That article is from 2007, while Google changed its logs policy in 2008. Does anyone know if the new policy anonymizes full IP addresses, or just the last octet?
I think the fact that Google still uses the phrase "anonymizing IP addresses" as opposed to logs or queries speaks for itself. If they spoke of anonymizing logs or queries, that could imply the possibility of deleting IPs. But to "anonymize" an IP implies something weaker than deletion, otherwise they would just use that term.
